Telvonic SYSTEMSGPON & XGS-PON ONT production test. Optical, protocol and traffic in one pass.
A 16-DUT rack, two tiers of eight wired by PON fibre and LAN, with a PON tester, optical power meter, DCA scope and production OLT — including combo ONTs with Wi-Fi, voice and 10G Ethernet.
Devices per rack on two tiers of eight, each wired by PON fibre and LAN into one PON tester.
The line, in numbers.
SFU · HGU · comboWhat every ONT goes through
- Optical TX power, extinction ratio, RX sensitivity
- OLT registration, ranging and OMCI checks
- End-to-end traffic, voice and functional tests
Why this is hard to get right in-house.
Going deeper: GPON & XGS-PON ONT production test checklist
Three disciplines
Optical power, PON protocol and Wi-Fi RF are usually handled by different vendors and tools — leaving gaps in traceability.
Operator requirements
Service providers expect OMCI interoperability and TR-069 behaviour to be verified before units ship.
Volume and margin
ONTs are high-volume, low-margin products — every second of cycle time and every false fail matters.
Station by station.
A typical configuration. We split and parallelise stations to hit your units-per-hour target.
Optical test
TX optical power, extinction ratio and RX sensitivity, with eye-diagram checks on the DCA.
PON protocol
OLT registration, ranging, OMCI checks and IP traffic through the PON path.
Wi-Fi & functional
Wi-Fi calibration for combo units, Ethernet throughput, POTS / VoIP, USB, LEDs and buttons.
Final QC
GPON SN / MAC / password write and verify, label print and MES upload.

Questions engineers ask us
Which PON technologies do you support?
GPON, XG-PON, XGS-PON and EPON / 10G-EPON ONTs and ONUs, including combo units with Wi-Fi, voice and multi-gigabit Ethernet.
Do we need a real OLT on the line?
Not always. Depending on test coverage we use a production OLT or OLT emulation to verify registration, ranging, OMCI and end-to-end traffic.
Can one line test both the PON and Wi-Fi side of a combo ONT?
Yes — that is our speciality. Optical, protocol and Wi-Fi stations run under one Line Manager test plan with one serial-number record per unit.
